ReviewPharmacological rationale for tapentadol therapy: a review of new evidence.
Chronic pain could be considered as a neurological disorder. Therefore, appropriate selection of the therapy, which should consider the pathophysiological mechanisms of pain, can result in a successful analgesic outcome. Tapentadol is an analgesic drug which acts both as a μ-opioid receptor (MOR) agonist and as a noradrenaline reuptake inhibitor (NRI), thereby generating a synergistic action in terms of analgesic efficacy, but not for the burden of adverse effects. ⋯ This molecule holds the potential to address at least some of the current limitations of analgesic therapy due to its unique mechanism of action and has shown to be safe and effective in the treatment of chronic pain of cancer and noncancer etiologies including nociceptive, neuropathic and mixed pain. In particular, the MOR component of tapentadol activity predominantly allows for analgesia in nociceptive pain; on the other hand, the NRI component contributes, now in a predominant manner, for analgesic efficacy in cases of neuropathic pain states. This paper will discuss recent pieces of evidence on the pathophysiology of pain, the background on tapentadol and then present some new studies on how the unique mechanism of action of tapentadol provides a key role in its analgesic efficacy in a number of pain states and with a favorable safety profile.

ReviewTapentadol in the management of cancer pain: current evidence and future perspectives.
Thanks to the progress in early diagnosis and treatment of cancer, the life expectancy of cancer patients has now increased. Patients are, therefore, more likely to experience their individual cancer pain as a chronic pain. As a consequence, long-term treatment of cancer-related pain and oncological therapy-related pain are a major need for all patients and a challenge to all healthcare professionals. ⋯ In randomized, double-blind and active-controlled trials it proved non-inferior to standard opioids like morphine or oxycodone in the management of moderate-to-severe cancer pain, both in opioid-naive and in opioid-pretreated patients. The good analgesic efficacy may be partly due to the action of tapentadol on neuropathic pain components. Together with the low rate of gastrointestinal adverse effects and the overall favorable safety profile, tapentadol can be considered a good option in cancer pain patients, who can suffer frequently from nausea, vomiting, constipation or other events that further reduce their quality of life.

ReviewVirtual reality as an analgesic for acute and chronic pain in adults: a systematic review and meta-analysis.
Background: Previous studies have shown that virtual reality (VR) is effective in reducing acute and chronic pain both in adults and in children. Given the emergence of new VR technology, and the growing body of research surrounding VR and pain management, an updated systematic review is warranted. Purpose: The purpose of this systematic review is to compare the effectiveness of VR in reducing acute and chronic pain in adults. ⋯ Limitations: Due to heterogeneity, we were unable to perform meta-analyses for all study populations and pain conditions. Conclusions: VR is an effective treatment for reducing acute pain. There is some research that suggests VR can reduce chronic pain during the intervention; however, more evidence is needed to conclude that VR is effective for lasting reductions in chronic pain.

ReviewSafety And Efficacy Of The Unique Opioid Buprenorphine For The Treatment Of Chronic Pain.
Chronic pain is associated with decreased quality of life and is one of the most common reasons adults seek medical care, making treatment imperative for many aspects of patient well-being. Chronic pain management typically involves the use of Schedule II full μ-opioid receptor agonists for pain relief; however, the increasing prevalence of opioid addiction is a national crisis that is impacting public health and social and economic welfare. Buprenorphine is a Schedule III partial μ-opioid receptor agonist that is an equally effective but potentially safer treatment option for chronic pain than full μ-opioid receptor agonists. The purpose of this review is to provide an overview of the clinical efficacy and safety of the transdermal and buccal formulations of buprenorphine, which are approved by the Food and Drug Administration for chronic pain, compared with that of extended-release full μ-opioid receptor agonists. ⋯ Comparison of current clinical data along with results of responder and safety analyses support the use of buprenorphine over full μ-opioid receptor agonists for effective preferential treatment of chronic pain; however, head-to-head clinical studies are warranted.

ReviewTapentadol in the treatment of osteoarthritis: pharmacological rationale and clinical evidence.
Osteoarthritis (OA) is the most prevalent joint disease in older people worldwide. Pain owing to OA is considered one of the most frequent causes of chronic pain; however, current pharmacological approaches have some limitations in terms of efficacy and safety. ⋯ Tapentadol is an analgesic molecule, which combines two synergistic mechanisms of action, MOR, and norepinephrine reuptake inhibition. This narrative review will briefly discuss the mechanisms contributing to the onset and maintenance of pain in OA patients; clinical data on the use of tapentadol in this setting will then be presented and commented.
